20 Awesome Solar-Powered Homes

Update 10/16/2009: See the completed 20 Solar Decathlon Homes of 2009.

For three weeks in October, the U.S. Department of Energy will host the biennial Solar Decathlon at the National Mall in Washington, D.C.  The Solar Decathlon is a competition of 20 teams of college and university students to design, build, and operate the most attractive, effective, and energy-efficient solar-powered house.  There are 10 subjective and objective contests in these categories: architecture, market viability, engineering, lighting design, communications, comfort zone, hot water, appliances, home entertainment, and net metering. 

The competition furthers several different goals -- to educate students and the public, to help promote solar technologies, to promote whole building design, and to demonstrate the potential for net zero energy homes.  Plus, the homes are beautiful and exciting.  They're completely solar-powered, and we'll take a more exhaustive look at the fully constructed homes soon.  In the meantime, here's a preview of each home.  Any thoughts on an early leader?
